In the first season of Letters & Numbers, our focus is on books, starting with a mini-series on publishers and platforms. In this first episode, we answer the deceptively simple question, how many publishers are there - really? Hundreds? Thousands? The answer may surprise - and alarm - you.

Join author, linguist, and mathematician-in-the-making Sarah on an exploration of the world through the lens of letters and numbers!
